<!-- speakable-start -->
> **Bottom Line:** Star Exposure Calculator serves as a stable technical reference, but the lack of development velocity risks obsolescence as new camera sensors enter the market.
<!-- speakable-end -->

**Best for:** Astrophotographers and telescope users requiring precise exposure and optical calculations.

<!-- section:pm-actions -->
### PM Action Plan (Next Best Moves)

- [ ] [MAINTAIN] Update camera database because sensor technology evolves rapidly → maintain technical relevance
<!-- /section:pm-actions -->

<!-- section:outlook -->
### Outlook: Stable

The astrophotography utility market remains stable, but success depends on keeping pace with hardware sensor specifications. Star Exposure Calculator's current maintenance posture risks losing users to rivals who offer more frequent database updates.

- ⚪ The maintenance-only release cadence suggests the developer is prioritizing stability over new feature expansion, which limits growth potential.
